Somewhere, back behind the cobwebs of my brain, I remember a movie in which someone used gun powder instead of baking powder. The results were explosive, naturally, but that is as far I my memory goes. It must have been Buster Keaton, or Laurel and Hardy, or Lou Costella, or The Three Stooges, because who else would do a thing like that? Gilligan hadn't been invented yet.
